Detailed Forecast

Synopsis

A pattern featuring daytime sea breezes and overnight land breezes will prevail across most of the state through the middle of next week. Expect afternoon clouds and a few showers over mauka and interior areas each day, with a few mainly windward showers each night. A weakening front may increase clouds and showers Monday night through Wednesday of next week.

Discussion

Currently at the surface, a 1030 mb high is centered around 2100 miles northeast of Honolulu, with a ridge extending southwestward to a location near or just north of Kauai. The resulting gradient is weak enough for land breezes across the western islands, while light to moderate trade winds prevail over the eastern end of the state. Infrared satellite imagery shows partly to mostly cloudy conditions, primarily due to high clouds moving through. Radar imagery shows a few showers over Maui County and the Big Island, with rain free conditions elsewhere.
The ridge of high pressure will remain nearly stationary near or just north of Kauai today. Light and variable winds will persist over Kauai and Oahu allowing for sea breeze development, while light to moderate trades hold over the eastern end of the state. The high will then settle southward and linger over the island chain this weekend through the middle of next week. This will result in an extended period of light and variable winds featuring daytime sea breezes and overnight land breezes statewide.
As for the remaining weather details, fairly dry conditions will prevail through the middle of next week, with no significant rainfall expected. A few showers are expected to develop over the island interiors each afternoon, while nights and mornings will be mostly dry aside from a few mainly windward focused showers. A weakening front approaching from the northwest could bring a slight increase in showers Monday night through Wednesday of next week.

Aviation

As a surface ridge remains in the vicinity of the islands, winds will continue in the light to moderate range statewide. And many areas will see daytime sea breezes and nighttime land breezes. Showers will mainly develop in the afternoon and evening hours over interior and mauka sections, though in most locales VFR will hold sway.
No AIRMETs are in effect, and none are anticipated through the day.

Marine

Light and variable winds are here to stay through early next week over the Kauai and Oahu waters as the surface ridge remains in the area. For the eastern end of the state, moderate to fresh east- southeast winds will hold today, then drop off into the light category through the weekend.
Surf along exposed north and west facing shores will remain around to above average through the weekend as overlapping, west-northwest swells arrive and move through in response to the ongoing active pattern across the northern Pacific. The west-northwest swell that arrived Thursday will hold today before easing into the weekend. Seas associated with this swell will hover around the Small Craft Advisory level of 10 ft across the exposed waters, which will likely continue through Saturday. Latest observations at the offshore buoys to the northwest continue run above predicted levels this morning, with the peak energy holding in the 12-13 second bands. This energy extrapolated to the exposed north and west facing shores supports the High Surf Advisory continuing today.
As this swell slowly eases into tonight, the next pulse associated with a compact, hurricane-force low that crossed the Date Line around 500 NM north of Midway earlier Thursday is forecast to arrive late tonight into Saturday, which will drive the surf back toward warning levels (seas likely exceeding the Small Craft Advisory level of 10 ft over exposed waters) for exposed coasts of the smaller islands. A gradual downward trend is then expected late Sunday through Monday, as this source moves out.
For the extended period (next week), expect the winter mode to continue as a broad area low pressure, encompassing much of the far northwest Pacific, becomes established this weekend into next week. Guidance depicts the associated fetch expanding eastward within the 290 and 310 degree directional bands relative to the islands, driving the seas to around 25 ft. If this materializes, expect an upward trend in surf/swell locally through the day Tuesday, which could persist into the second half of next week.
